I'm trying to press pull sketch and it goes down instead of going horizontal And it cuts like that not even whole body.
I want to get something like that

Hi @zakariadze1,

If you could share your design here, you'll get lots of help.

But, a short answer to your immediate question is:  Extrude is defaulting to "Cut" because the profile intersects the existing body.  You can override that, however, by just choosing "Join" instead from the Extrude dialog:

Sorry - post went twice - network hiccup.

I want my sketch to extrude like you do but it goes like arch not straight 

Yellow lines show how I want it to go and Blue lines show how it goes, as you see its like curvy

You might be able to visualize the problem better if you extrude with a join.  That part of the cut droops down because your profile is sloped, and your cutting into  curved surface.  It's doing exactly what you are telling it to do.  Look at it normal to the plane, might be easer to visualize.

Hi @zakariadze1,

Another approach you can use to get that straight line around your cylinder, you could use Revolve instead of Extrude:
